Product Overview
The 106-PGM and S106-PGM series control valves are designed for particularly sensitive applications
or situations where valves are difficult to access and maintain.
The PGM series control valves provide integral back-up control and the ability to signal should the
desired function move off limits. It can also provide an independent and very positive override.
It is a variation of the standard single chamber 106-PG valve with modifications that add the following
features:
•t Back-up diaphragm
•t Completely self-contained
•t Modulating or emergency close back-up
•t Back-up components kept out of the main stream until required
•t Extremely positive shut-off
•t Emergency close for security breach or earthquake
With SRD technology the valve becomes incredibly steady throughout a complete range of flows and
eradicates the need of additional low flow bypass valves.
The PGM series control valves may be combined with additional Singer Valve specific accessories to
add further customization such as:
•t Back-up pilot system
•t Annunciation with an Single Pole Double Throw Limit Switch
Refer to Main Valve Options on page 75 and Pilots & Accessories on page 259 to customize the valve
to suit specific applications.
